✦ Synopsis

Angular leaf spot (Isariqsisgriseola SACC.) is a serious disease of French bean in the hills of India and 40 to 70 per cent of the green pods are damaged and rendered unmarketable. Crosses were made between PLB 257, (Phaseolus coccineus L.), a red flowering pole type, resistant to angular leaf spot, and Contender (Phaseolus vulgaris L.), a highly susceptible commercial cultivar. Studies of the F,, F,, and F, progenies indicated that PLB 257, carries a recessive gene imparting resistance to angular leaf spot. 1NTRODUCTlON
